History NightmareFuel / ShaunOfTheDead

* The events around Shaun's mum. There's the bit where you see her arm with a gaping hole in it, Shaun having to rush away from zombies invading their safehouse to watch his mum die, convulsing as she does. The off-screen shotgun-cocking sound just afterwards, with one of his "friends" pointing a shotgun (rightly, but tactlessly) at her. And then being handed a gun and told to shoot your own mother, and the effect when her face changes just before he does.

* Some of the background events such as the well-dressed man running away from ''something'' as Shaun buys flowers; the homeless man who grabs a pigeon and ''raises it to his mouth'' -- and then a bus goes by; and then the couple outside the Winchester who appear to be making out... ''and then the guy's head falls so far backwards that it dangles against his back....''

* The last few minutes as we realize one of the survivors has [[spoiler: gone around the deep end]].

* The lights being switched on in the back room of the Winchester. We're expecting, when Shaun goes into a dark room alone, that he'll be attacked by a stray zombie trapped in there. We don't expect that when he switches on the lights there are ''dozens and dozens of gore-smeared zombies pawing at the backdoor's window'' moaning and groaning. ''His knee-jerk reaction of turning off the lights and pulling down the shade somehow makes it worse, because now they're out of sight but ''definitely'' not out of mind. When Shaun is about to leave, another door in the room starts to shake. During the "Don't Stop Me Now" scene, David runs into that zombie when trying to switch off the fuses.

* Near the end of the film, David is dragged through a window by zombies kicking and screaming, and is gruesomely [[DevouredByTheHorde disemboweled, torn limb from limb, and eaten alive]]. Sure, he's [[AssholeVictim the film's most detestable character]], which makes his demise less unfunny than most others, but the last moment of his life were pure terror, hopelessness, and pain. He died almost instantly upon being paunched, so his suffering was short-lived, but still, what a horrific, embarrassing way to go.

* While Shaun and Ed are driving to collect Barbara and deal with Phillip, they pass an ambulance with a couple of paramedics lying sprawled out in the road, the back doors burst open and a full bodybag strapped to a stretcher that's half out of the back of the vehicle. Only...the bodybag is moving. Not just moving but practically ''convulsing'' as the body inside is clearly attempting to claw its way out. It's a very brief shot (less than five seconds long) but it's still very disturbing; it even audibly freaked out both Bill Nighy and Penelope Wilton on their commentary track.

* Near the end of the film, David is dragged through a window by zombies kicking and screaming, and is gruesomely disemboweled, torn limb from limb, and eaten alive. Ouch.
** Sure, he's the films most detestable character (making his demise less unfunny than most others), but the last moment of his life were pure terror, hopelessness and pain. He died almost instantly upon being paunched, so his suffering was short lived. Still, what a horrific, embarrassing way to go.
** Poor Dianne had it rough after this scene. She tried to fight her way through the undead horde using David's leg as a bat to save him only to realize it was far too late and her only chance of survival was to climb into a tree where she spent several days with only David's leg as sustenance.

* Shaun seeing a horde of zombies devouring one of the regulars from the Winchester, the man with the snakeskin boots. It's how he realizes they're on the right track to the pub.

** What's worse is that Shaun unintentionally led them back to the Winchester. He thought he gave them the slip by hiding in a rubbish bin, but one zombie spotted him run off.
